The Future of Analog IC Technology
MPM3805
6V Input, 0.6A Module
Synchronous Step-Down Converter
with Integrated Inductor
DESCRIPTION
The MPM3805 is a step-down module converter
with built-in power MOSFETs and inductor. The
module’s integrated inductor simplifies the power
system design and provides easy, efficient use.
The DC-DC module comes in a small surface-
mount QFN-12 (2.5mmx3.0mmx0.9mm) package
and achieves 0.6A continuous output current
from a 2.5V to 6V input voltage with excellent
load and line regulation. The output voltage is
regulated as low as 0.6V. For adjustable output,
only FB resistors and input and output capacitors
are needed to complete the design.
The Constant-on-time control (COT) scheme
provides fast transient response and eases loop
stabilization. Fault condition protection includes
cycle-by-cycle current limiting and thermal
shutdown (TSD).
The MPM3805 is ideal for a wide range of
applications including high performance DSPs,
FPGAs, PDAs, portable instruments and storage.
